AKA Double Pendulum Valve, Double Gate Valve, Double Flap Gate, Double Dump Valves, Tipping valves, Trickle valves - all names used to refer to the product we invented more than 60 years ago. The equipment may go by other names, but there is only one Plattco Double Flap Airlock valve!
The Pollution Control (PCV) Valve provides a lower cost alternative that is perfect for pollution control systems and other low pressure (up to 2 ps/.14 bar) applications, with the same low profile as the S8-Series.
The pollution control valve is perfect for use in low pressure applications. Replace your existing rotary valves and get the reliable, long-wearing performance of our pollution control valve in applications using highly abrasive or high temperature materials. Our patented design eliminates internal bridging, plugging, jamming, and material build-up.
Since we invented the double flap airlock valve in the 1960s, we've made our living not only in critical applications maintaining an airlock under high pressure, high temperatures, or any other demanding environment, but by essentially replacing rotary valves in many industries.
Combined with Plattco’s legendary Easy Maintenance Technology, this exceptional radial valve offers the lowest overall 10 year cost of any other airlock on the market.
Ideal for dry material handling with successful applications in industries around the world. The robust design of the H-Series is the perfect selection for large volume, large particle sizes, and the most demanding conditions. Rated for up to 40 PSI (2.75 Bar) and temperatures up to 1800F/980C.Learn More
Same features of the H-Series with an air tight radial (round) opening with round internal mating components (seat/flapper). This valve received its name based on its round (radial) opening. Rated for up to 40 PSI (2.75 Bar) and temperatures up to 1800F/980C.Learn More
Same rugged design as our famous H-Series Flap Valve at roughly half the height for applications when headroom is restricted. This valve is named for its “S”horter profile than our original H-Series. Rated for up to 15 PSI (1.0 Bar) and temperatures up to 1800F/980C.Learn More
The perfect valve for pollution control systems and other low pressure differential (< 2 psi/.14 bar) applications, with the same profile as the S8-Series. Rated for up to 750F/400C.Learn More
